Preface

In the process of marketing customer acquisition, data collection or customer management, many companies will organize mobile phone number data from TXT files .

For example:

Customer contact information scraped from web page

List of numbers exported from database

Customer mobile phone number compiled from chat history

User data exported from marketing platform

These data are often saved as TXT text files .

But the numbers in TXT files are usually very messy, for example:

Numbers mixed with text

The same number appears repeatedly

Number format is not uniform

Contains invalid number

If these data are used directly for marketing or customer management, efficiency will be seriously affected. Therefore, extracting and cleaning mobile phone numbers in batches is a very important step.

Frequently asked questions about TXT mobile phone number data

In actual work, the mobile phone number in the TXT file usually has the following situations.

Numbers are mixed in with the text content

Many TXT files are not specialized number lists, for example:

Customer A: +1 202 555 0123
Customer B: +44 7700 900123
Contact number: 13812345678

In this case, the mobile phone number data needs to be extracted first and then sorted.

There are a lot of duplicate numbers

When sorting data, the same number may be recorded multiple times, for example:

+12025550123
+12025550123
+12025550123

If deduplication is not performed:

Customers may receive duplicate marketing messages

Data analysis will be biased

increased marketing costs

Therefore, numbers need to be deduplicated in batches.

Number format is confusing

Data from different sources may exist in different formats, for example:

+1 202 555 0123
12025550123
202-555-0123
(202)5550123

Although it is the same number, the system may recognize it as a different number.

The number cleaning tool can unify the format.

Why is it not recommended to organize TXT numbers manually?

Many people will try to organize TXT numbers manually, for example:

Copy to Excel

Manually remove duplicate data

Manually modify the format

But when the number of numbers reaches thousands or even tens of thousands , this method is very time-consuming.

Frequently asked questions include:

Sorting takes too long

prone to human error

Data formats are still not uniform

Therefore, a more efficient way is to use professional number cleaning tools .
